Table of Contents � Introduction to LIN � LIN Characteristics � Data Transport � Frames � Our Application
� Local Interconnect Network (LIN) � Single master with multiple slaves provides communication between controllers, sensors, actuators and the software
� LIN 2.0 � LIN J2602
Introduc2on
LIN Characteris2cs � Self synchronization without a quartz or ceramic resonator in the slave nodes
� Signal propagation time computable in advance � Speed up to 20 Kbit/s � Signal based application interaction
Master and Slave � A LIN cluster consists of one master task and several slave tasks.
Data Transport � Signals or diagnostic messages are transported in a frame � Signals are present at the same position of the data field for all frames � Tx signals � Rx signals
� Diagnostic messages are transported in frames with two reserved identifiers
Frames � The entities that are transferred on the LIN bus are frames
� A frame consists of a header and a response
Frame -‐ Header � Break � Synch � Protected identifier
Frames � Four types of frames: 1. Unconditional frame 2. Event triggered frame 3. Sporadic frame 4. Diagnostic frames
Real World Applica2on � MicroAutoBox � Actuators on a single LIN bus
